Re-derive an expression for average NuL (= hLL/k) for flow over a flat plate by integrating the expression for average hL for a mixed BL. For Rex,cr, use 123456 (keeping the same sequence), and find the constant B (in Eq. 7.38). Also show that for Rex,cr = 500,000, B is indeed equal to 871.
eq. 7.38=> NuL=(0.037 ReL^(4/5)-B)Pr^(1/3)
0.6<=Pr<=60
Rex,c <= ReL <=108

In a low temperature drying system, air at 60°C and 10% Relative humidity passes over a bed of diced carrots at 20 kg-dry air/sec. The rate of water removal from the carrots Is measured by difference in total weight over time and found to be approximately .16 kg-water/sec. In the system described above, calculate the temperature and relative humidity of the air exiting the drying system.

1a. The relative humdity outdoor is 70% and the outdoor temperature is 90 degree F what is the actual partial pressure of water vapor in the air
1b. Humidty ratio (w) is the ratio of the mass of the water (Mw) to the mass of dry air (Mw) note that two partial pressures sum to the total pressure (P =Pa + Pv) derive the equation
w = 0.622Pv / (P-Pv). Use the ideal gas equation for mass
1c. Solve for humidity ratio if the partial pressure of water vapor is 0.1816psia
1d. What is the relative humidity of 70 degree F moist air in a classroom
1e. Estimate the mass (Ibm) of water vapor in the classroom
